I turned right along the lane and followed it as far as a crossroads (rather unusually, Friendless Lane goes left here rather than straight on). I turned right, and followed Valley Lane down into a valley. In the valley bottom, where the lane turned right, I took a bridleway going left. After about half a mile along the valley bottom I reached the hamlet of Trowley Bottom.

I went diagonally across a staggered crossroads, and took Trowley Hill Road, heading uphill into Flamstead. I followed the road for just over half a mile, eventually passing Flamstead church on my right, and then turned left into the other end of Friendless Lane. The lane turned right by a junction with Mill Lane, and after another hundred yards or so I took a footpath on the right (the fingerpost said it was 1.5 miles to Markyate).

The path crossed part of a paddock, then followed a hedge on the right. In the field corner, the path turned right for a few yards and then left - it was now running between fences and overhanging hedges. I was pleased when the hedge on the left ended, and I could see out from the path on that side. A little further on I entered the corner of a large field (it sometimes has horses in it), where I went straight on, close to the hedgerow on my right. The path then continued past a smaller ploughed field, going through the hedgerow in the next field corner before turning left for a few yards. It then turned right, to follow a long headland between two very large fields for several hundred yards. After a while there was a hedge to my left, then a bit further on the path switched to the other side of the hedgerow. A few more hundred yards further on I reached a field corner, where the path had been recently resurfaced (red!) as it led into Markyate.
